Abstract:
The present invention provides a method for testing a photosensitive composition and a method for producing a photosensitive composition that can easily test whether or not the photosensitive composition exhibits a predetermined LWR. The method for testing a photosensitive composition has a step 1 of using a reference photosensitive composition including an acid decomposable resin having a group that is decomposed by an action of an acid to generate a polar group and a photoacid generator, to form a resist film on a substrate, exposing the resist film, using a developer to perform a development treatment to form a resist pattern, and obtaining any one reference data selected from the group consisting of a line width or a space width of a line-shaped resist pattern, an opening diameter of an opening portion in the resist pattern, and a dot diameter of a dot-like resist pattern; a step 2 of using a photosensitive composition for measurement including components of the same types as types of components included in the reference photosensitive composition, to form a resist film on a substrate, exposing the resist film, using a developer to perform a development treatment to form a resist pattern, and obtaining measurement data of the resist pattern; and a step 3 of performing comparison between the reference data and the measurement data to determine whether or not an allowable range is satisfied, wherein the developer is an organic solvent-based developer including an aliphatic hydrocarbon solvent, an aromatic hydrocarbon, and at least one metal atom selected from the group consisting of Al, Fe, and Ni, and a mass ratio of a content of the aromatic hydrocarbon to a content of the metal atom in the developer is 5.0×104 to 2.0×1010.

By monitoring the exterior temperature of the ducting, and having knowledge of the surrounding ambient air, principles of heat transfer, fluid flow and thermodynamics accurately determine the severity of diameter restriction on the inside of the ducting in terms of a layer of a substance coating the interior diameter or periphery of the duct or other conduit.
Abstract:
The invention relates to a method for determining material dimensions of a longitudinal profiled section (2) during a sawing process, in which a saw blade (3) is advanced, the longitudinal profiled section (2) being machined by said saw blade (3) along a saw groove during this time; advancement position data of said saw blade (3) along the advancement path (s) being determined and, during this sawing operation, additional measurement data being determined from the group of sawing force (Fs) or another variable which corresponds to the sawing force (Fs). The invention is characterised in that an actual profile is determined from the advancement position data and said additional measurement data.
Abstract:
The present invention relates to a bra fitting method for determining and presenting customized advice for bras. Compared to existing methods the present method is based on an optimized fitting of the bodily dimensions with the functional characteristics of a bra model. Applying a given technique, the present invention incorporates the functional characteristics, and in particular the lifting, shaping and covering of the bra in the brassiere measurement method. As such the method of the present invention results in a customized advice, allowing users to gain insights in the fitting requirements and providing them with a confidence to seek and identify a correctly fitting bra.

A device for inspecting rings and necks of containers includes a movable element with an outer gauge for checking the outside of the ring of the containers, and an inner gauge for checking the inside of the ring and neck of the containers. The movable element includes a system for measuring the position of the movable element relative to the frame, a system for detecting contact between the inner gauge and the container, a system for detecting contact between the outer gauge and the container, and a processing unit for determining, on the basis of the measurements of the position of the movable element and of the instances of contact between the gauges and the container, whether or not the size of the rings and/or necks of the containers are acceptable, and the types of defects for the containers whereof the sizes of the rings and/or necks are not acceptable.
Abstract:
A selection method for a strong wind region composite insulator based on structure parameters, and a composite insulator are disclosed. When a selection is made among a plurality of composite insulators according to the selection method, structure parameters of the composite insulators are measured first, and then the selection is made according to certain ranges of the parameters, a selected composite insulator is tested, and it is found that it may withstand strong wind climate environments where the highest wind speed reaches 50 m/s. The composite insulator is a composite insulator having corresponding structure parameters. The selection method is easy to operate and implement. When the composite insulator is applied to a strong wind region where the highest wind speed reaches 50 m/s, the problem of violent oscillation of umbrella skirts or tear of the umbrella skirts does not occur, and the composite insulator may still operate reliably.
Abstract:
A module for the dimensional analysis of a plate-holding cylinder includes a plurality of boxes, in table form, each of which corresponds to a surface portion of an outer surface of the plate-holding cylinder and is indicative of the dimensional deviation of a surface portion with respect to the nominal diameter of the plate-holding cylinder. A process and an apparatus for dimensional analysis of the plate-holding cylinder are also provided.
Abstract:
The present invention is directed to automated apparatuses and methods for measuring fastener hole depth, fastener length, countersink depth and/or hole diameters in a workpiece (or other object) in an automated and extremely rapid, efficient and accurate manner. The apparatuses may be operably connected with a power source and with one or a plurality of computers or other data collection devices to transmit fastener hole depth, countersink depth and/or hole diameter measurement data and/or information to them each time that a fastener hole is measured, while the apparatus is continuously measuring fastener holes (i.e., with no interruptions). Extremely advantageously, using only one hand, and by only squeezing a trigger only one time, an operator of such an apparatus may successfully and very rapidly and accurately perform more than one, or all three, of the following functions: (i) normalize the apparatus relative to one or a plurality of fastener holes and/or workpiece surfaces; (ii) make one or a plurality of accurate measurements; and (iii) transmit the one or more measurements from the apparatus to one or a plurality of computers and/or other data collection devices for, for example, recordation, storage, manipulation, other use and/or the like.
Abstract:
In order to be able to measure a diameter in a turning machine without rotating a workpiece and thus prevent circularity and concentricity errors from entering into the diameter determination, it is proposed according to the invention to use a measuring device that is movable in both transversal directions relative to the rotation axis, thus in the X-direction and also in the Y-direction, wherein the measuring device can scan the workpiece from both sides in one clamping step without rotating the workpiece.
